Author really went "I'm bored, time for some manufactured drama"
Manga authors are so bad at fucking writing. Like this is the most blatant, cheapest and most unnecessary bullshit ever. Wish the author an axe for their serialisation so they write their next story with more thought.
Let me clarify, I'm not even mad about the fact that every story with these type of characters has the arranged marriage bs, it's overdone, boring and never has a good payoff, but whatever I'm sure we're used to it.
But the fucking way the author decided to do it is almost fucking comical lol. They can still be redeemed by providing a quick resolution, but man...
